Congratulations, that is for sure a genuine feeling after your very first purchase of Bitcoin and be consistent to all of what you've said if you're planning to accumulate more on a monthly basis or whenever you're available to.
I believe the amount of knowledge I have accumulated about bitcoin through this forum will strengthened my emotion not to panic when the market goes bearish.
It is not going to be easy if you experience the bearish moment of the market but you have to experience that and to see how you're going to react on it. But don't you worry for now because we're done on its cycle as of the moment and we're approaching the halving which is the indication that we're near in a bull run. Keep it up.
